The reason why someone should like this film is that its director Claude Mouriéras has given a unique opportunity of his life to famous actor Michel Piccoli to portray the role of an old man whose unexpected arrival causes tremendous turmoil in the mundane lives of his three daughters.It is a veritable tragedy when we see how an old gentleman is ill treated by his daughters.This brief description might suggest that this film is the French cousin of the famous Italian film "Tre Fratelli" directed by great director Francesco Rosi.There is hardly any similarity between these two films.In France a lot of films are made annually which give viewers a glimpse of French family life but it is a mystery as to how many of them are seen by people outside of France. Tout va bien,on s'en va is an exception to this rule as it has been shown in many film festivals.Apart from Michel Piccoli's mind boggling performance,one should see how other actresses perform in front of the camera.A film which will surely move you to tears when you see how cruel Miou Miou,Sandrine Kiberlain and Natacha Régnier have been in this film opposite their father Michel Piccoli.If you like this film,make sure to watch two others French films "Daddy Nostalgie" and "Un dimanche à la campagne" both directed by Bertrand Tavernier.He is the only leading figure of French cinema whose has made films about families which can be appreciated within a family setup.
